Problems solved by technology

Studies have shown that in the needle punching process, steel needles with hooks puncture the fiber web for entanglement and compounding, which will cut off a large number of fibers and reinforce the filaments of the base fabric, resulting in inevitable damage to the base fabric, which will eventually cause a decrease in the mechanical strength of the filter

Embodiment Construction

[0031] The production process of the spunlace composite high-temperature-resistant and corrosion-resistant filter material of the present invention uses polyphenylene sulfide fiber and glass fiber base cloth as raw materials; the polyphenylene sulfide fiber is first inspected, weighed and fed, and then fed into the long curtain in sequence , horizontal opener, large warehouse mixing box, fine opener, and then carding machine 1 and carding machine 2 perform layered carding, and then enter the cross-lapper 1 and cross-lapper 2 respectively for laying Then the glass fiber base cloth is sandwiched between the raw materials conveyed by the first cross-lapper and the second cross-lapper and laminated, and then enters the pre-wet process, spunlace process, dehydration process, and drying process in sequence. Drying process, coiling process.

[0032] Among them, carding machine one, the main cylinder work roll is 110m / min, the main cylinder stripping roll is 150m / min, the main cylinde...

Abstract

The invention relates to a production process for a spunlace composite high temperature-resisting and corrosion-resisting filtering material and belongs to the technical field of a textile filtering material. The production process comprises the following steps that: taking polyphenylene sulfide fibers and fiberglass fabrics as raw materials; checking, weighing and charging the polyphenylene sulfide fibers; charging the polyphenylene sulfide fibers into a long curtain, a horizontal opener, a big-cabin cotton blending box and a refined opener successively; and then carding by using a carding machine I and a carding machine II in a layering mode; placing into a cross lapping machine I and a cross lapping machine II to lap; clamping the fiberglass fabrics between the raw materials delivered by the cross lapping machine I and the cross lapping machine II and performing superposition; and performing the processes of pre-wetting, hydroentangling, dehydrating, drying and taking-up. The production process for the spunlace composite high temperature-resisting and corrosion-resisting filtering material provided by the invention has the advantages of excellent mechanical performance, filtration performance, high temperature-resisting performance, and chemical corrosion-resisting performance and size stability.

Description

technical field [0001] The invention relates to a production process of a spunlace composite high-temperature-resistant and corrosion-resistant filter material, which belongs to the technical field of textile filter materials. Background technique [0002] With the progress of society, people's living standards have been significantly improved. However, while high-tech brings wealth and a more convenient and comfortable life, it also brings many problems to the natural environment on which human beings depend. The environmental pollution caused by high-temperature dusty waste gas discharged from coal-fired power plants, steel industry, cement chemical industry, etc. has brought more and more harm to human survival and health. China's "Eleventh Five-Year Plan" puts forward the idea of ​​greatly increasing power generation capacity. It is necessary to increase the installed capacity of power generation to 910 million kilowatts by 2020, including thermal power generation of 60...
